Bed bugs are a growing problem in schools and daycares. Typically they are introduced by students or staff living with an infestation at home. Pinpointing where the bugs exist can be challenging in such environments since there are no beds or sleeping areas for the insects to congregate. (Similar challenges occur when bed bugs are found in offices, libraries and retail stores.) Usually only small numbers of bed bugs are spotted, often on a student’s clothing, backpack, chair or desk. While this does not necessarily confirm that the child’s residence also has bed bugs, the parents should be notified that the home should be inspected, preferably by a professional. Teachers, nurses, and staff should be educated about the bugs and what they look like. Bed bugs should also be considered if a student frequently has reddened itchy welts --but keep in mind such reactions can be for reasons other than bed bugs.
Hiring a pro to wipe out bed bugs isn’t cheap. Expect to pay about $200 per room to kill bed bugs, and you’ll likely need a few chemical treatments in order to eradicate bed bugs. Professional heat treatments will cost even more. And even if you hire a pro, you’ll still have to do lots of work yourself (moving furniture, washing all clothes, etc.). So consider declaring a DIY war on bed bugs. If you’re willing to spend $100 to $200 and do things right, your chances of success are excellent.
Treat other areas in your home. This is perhaps the most challenging part of do-it-yourself bed bug control. If you catch an infestation early you may not need to do anything more than treat and isolate your bed as described above. But if an infestation has spread to other parts of the home, bed isolation may not be good enough. Here is where professional help may be needed, especially if you’re not up to moving furniture. Still determined? Here are some tips that may improve your chances of success:
Some patients develop blisters filled with blood or bloody fluid, especially on the arms and legs. These blood blisters are extremely rare and can burst, causing bleeding or oozing of the bloody fluid. Healthcare providers are not sure if the cause of these blisters is related to the bug or the human but have found groups of patients that were all bitten by bugs on the same train exhibiting this sign.
Next, apply a bed bug powder into confined areas where it won’t be stirred up into the air. Places like the edges of carpeting, inside deep cracks and wall voids, and inside electrical outlets and light switches (accessed by removing the faceplate with a screwdriver) are good candidates for powders, as sprays can’t reach into these areas quite as well. We recommend using a professional powder applicator, which offers better control when applying the powder.
Although most furnishings need not be discarded, in some cases this may be necessary. This is especially true of heavily infested beds, sofas and recliners where bugs and eggs often reside in hard-to-reach places. Consequently, pest control firms may recommend such items be discarded, especially when in poor condition. When infested items are discarded, bagging or wrapping them prevents dislodgement of bugs en route to the trash.
If you suspect that bed bugs might be hiding in items that can’t be laundered or steamed, like books, papers, luggage, shoes, and dry-clean only clothing, you can treat those with a portable bed bug heater. Heaters are a popular way to safely heat-treat items during bed bug treatments, or as a preventative tool for travelers who want to ensure that bed bugs can’t escape from their luggage to infest their home.
Treat or isolate your bagged items. For washable items research shows that dry cleaning, washing in hot water for 30 minutes, or tumble drying for 30 minutes on high will kill all stages of bed bugs. Non-washables are a little trickier. Items that aren’t needed for a while can just be stored. It takes 2-5 months to kill bed bugs by isolating them in bags (the warmer the temperature, the shorter the survival time for starving bed bugs). Heating bags by placing in direct sunlight is one of the most effective methods during the warm summer months. Seven pounds of items placed in clear bags in direct sunlight on a 95 degree day will get hot enough to kill all bed bug life stages in one afternoon. Also, placing bagged items in a chest freezer (0 degrees F) for 8-10 hours is lethal for bed bugs and their eggs. Some toys may be disinfested by cleaning with hot soapy water and/or rubbing alcohol.
To treat an allergic reaction, the doctor may prescribe an antihistamine, corticosteroid, or epinephrine injection. If the area is infected, he or she might prescribe an antibiotic or recommend an over-the-counter antiseptic. Finally, if it’s severe itchiness that you’re dealing with, applying corticosteroid or taking an antihistamine in pill or liquid form may be able to help.
Bed bugs are attracted to their hosts primarily by carbon dioxide, secondarily by warmth, and also by certain chemicals. Cimex lectularius only feeds every five to seven days, which suggests that it does not spend the majority of its life searching for a host. When a bed bug is starved, it leaves its shelter and searches for a host. It returns to its shelter after successful feeding or if it encounters exposure to light. Cimex lectularius aggregate under all life stages and mating conditions. Bed bugs may choose to aggregate because of predation, resistance to desiccation, and more opportunities to find a mate. Airborne pheromones are responsible for aggregations.
The exact causes of this resurgence remain unclear; it is variously ascribed to greater foreign travel, increased immigration from the developing world to the developed world, more frequent exchange of second-hand furnishings among homes, a greater focus on control of other pests, resulting in neglect of bed bug countermeasures, and increasing resistance to pesticides. Declines in household cockroach populations that have resulted from the use of insecticides effective against this major bed bug predator have aided the bed bugs' resurgence, as have bans on DDT and other potent pesticides.[medical citation needed]
Perhaps more than any other structural pest, the bed bug illustrates the need for an integrated pest management (IPM) approach. IPM employs not a single method, such as pesticide application alone, but combines several of the best means of control, often adopting less hazardous and more effective pest management. Thus the best bed bug management plans incorporate more than one of the effective control methods listed below.
"By every metric that we use, it's getting worse and worse," says Coby Schal, an entomologist at North Carolina State University in Raleigh. Health authorities and pest control operators are regularly flooded with calls, and the epidemic may not have yet peaked. And because bedbugs are indoor pests, there are no high or low seasons throughout the year, he adds, only continual bombardment. "It's just the beginning of the problem in the U.S.," Schal says.
Systematically treat the room–all cracks and crevices around windows, outlets, blinds, pictures, posters and clocks on walls, baseboards, under edges of carpets and any other crevices or void areas in the room. Remember that immature bed bugs are very tiny. Dozens of bed bugs can hide in a recessed screw hole in a bed frame or dresser. Therefore it’s important that no hiding place be overlooked. Treatment can include vacuuming, but should not be limited to vacuuming only. Vacuums do not remove eggs, and will likely not remove all bed bugs from deeply infested cracks and crevices. Vacuums can remove many bed bugs from mattresses and the exterior of box springs (remember to immediately double-bag the vacuum bag after cleaning and dispose of outside in a trash can or dumpster). Sticky tape is another method of picking up bed bugs from furniture, walls, etc.
* Typically used for control of wood-destroying organisms, true fumigation of structures is occasionally performed for bed bug control. Fumigating a structure involves “tenting” it, i.e., draping and sealing it with tarps so that the fumigant, a poisonous gas, can be applied into and contained within the structure where it penetrates the contents and kills all pests within. Like whole-room heat treatments, fumigation has no lasting effect (it leaves no pesticide residue), is labor-intensive, and can damage contents. It is also more expensive, especially in northern states where fumigations are done less frequently. The advantage of fumigation over heat treatment may be that fumigation is more likely to kill all the pests within a structure.
Some bed bug species are parasites of bats or birds, and may bite people if the wild hosts are no longer available. Although similar in overall appearance, the species of bed bugs that normally feed on bats, swallows, chimney swifts, pigeons or other wild hosts can be differentiated from those that prefer humans. Entomologists and knowledgeable pest managers can make this determination. If bat bugs or bird bugs are present, roosting and nesting sites should be the primary focus, and the animals should be removed and excluded from the building.
One method of applying freezing temperatures to bed bugs entails the use of carbon dioxide (CO2) applied as “snow” with a portable application device, i.e., Cryonite™. When applied directly onto bed bugs, the frozen CO2 will kill them. However, this method is similar to using contact pesticides, that is, there is no residual activity. It can kill only as many bed bugs as the applicator can find. The advantage of using this type of freezing device is that bed bugs may be killed quickly and without the use of more hazardous pesticides. Again, this is not a stand-alone treatment, and it is recommended that it be used as a supplemental to the application of residual pesticides and/or other means of control.
Did you or someone else in your home recently come home from a trip? Bugs can stow away in clothing and in the recesses of your luggage. A good preventative measure is to check lodging you are staying in immediately after arrival. As mentioned before, signs are evident, even during the daytime, include the blood-colored excrement they leave behind.
Wash the bites with soap and water. Wash the area with mild soap and water; use a bar of soap and enough water to wet surface of your hands. Work the soap in your hands into thick, soapy lather. Rub the lather over the affected area liberally. Repeat until the entire area is covered. Leave on and do not rinse. Allow the soap lather to dry over the bitten areas. You should experience immediate relief from itching.

Everything you need to know about bedbugs Bedbugs are small wingless insects that feed exclusively on the blood of warm-blooded animals. They need to feed regularly to reproduce, lay eggs, and survive. Two species eat human blood, usually feeding during the night. In this article, we explain the typical signs of bedbugs in the home and how to remove them. Read now
The decline of bed bug populations in the 20th century is often credited to potent pesticides that had not previously been widely available. Other contributing factors that are less frequently mentioned in news reports are increased public awareness and slum clearance programs that combined pesticide use with steam disinfection, relocation of slum dwellers to new housing, and in some cases also follow-up inspections for several months after relocated tenants moved into their new housing.
To use sprays effectively to eliminate all traces of bed bugs, you need to know the signs of a bed bug infestation. The first sign that you may have bedbugs are some itchy bite marks on your skin when you wake up in the morning. Dr. Carol DerSarkissian on WebMD says that the bites from bed bugs cause red itchy bumps on the skin.3 You can learn about their other signs and symptoms in my articles on what do bed bug bites look like.
The bites themselves don't usually pose any major health risk since bedbugs are not known to spread diseases, but an allergic reaction to the bites may require medical attention, CDC officials say. There have also been some strange cases linked to bedbug infestations. Researchers reported in the Canadian Medical Association Journal in 2009 that they treated a 60-year-old man for anemia caused by blood loss from bedbug bites. Another study published in 1991 in the Journal of the Egyptian Society of Parasitology found that people with asthma might be more susceptible to allergic reactions from bedbug bites.
A few decades ago, bedbugs were somewhat of a novelty in developed countries. But since the early 2000s, infestations have become more common in places like the United States, Canada, the United Kingdom and Europe, according to the U.S. Centers for Disease Control and Prevention (CDC). A 2013 study in the journal Nature Scientific Reports suggested that bedbugs have evolved ways to resist insecticides.
People don't often consider bed bugs until they've left their mark. The appearance of flat, red welts in zigzag lines or small clusters is a key sign of bed bugs on humans. Bed bugs can also leave their bites in straight rows and, while they don't spread diseases to humans, their bites are quite irritating and scratching them can lead to bleeding and infection.
